Subscribers and MAC Access Control

MAC Access Control does not prevent wireless clients from associating with an Access Point but it does prevent
unauthorized clients from communicating with the Access Point. For example, the client software on a blocked
wireless subscriber will report that the card is linked to the AP but the AP (acting as a DHCP server) will not assign the
client an IP address.
Validation within the MAC Access Control Table occurs before a client is authenticated by the AP-2500 using internal
or external authentication (see AP-2500 Authentication Methods for an explanation of these options). For example, a
subscriber whose card is blocked by the MAC Access Control Table will never be given the opportunity to logon to the
Internet even if he has a valid User Name and Password.
